Which is a loop with two exit points.
As there is a simple mapping between stack operators and stackFlow diagrams
in Forth, so there is a simple relationship between control flow diagrams and
control flow words.

I am indebted to Wil Baden for having made this relationship clear, and use his
&quotflowgraphs&quot on this page to illustrate that mapping.

In the next section we look at how stackFlow diagrams can be combined with
flowgraphs, and see some applications of control flow words.
